ABSTRACT:
A damping device comprises a device (4, 7) for determining a mechanical state variable (ΔαMODEL, ΔαACTUAL) reproducing the torsion of a drivetrain (3) of an internal combustion engine (1) and an actuator (2) to activate an internal combustion engine (1) with a control variable as a function of the mechanical state variable (ΔαMODEL, ΔαACTUAL). It is proposed that the mechanical state variable (ΔαMODEL, ΔαACTUAL) be determined by a predictor element (4) that contains a model of the drivetrain (3) and/or the internal combustion engine (1).
